Biology & Habitat

Appearance

The body of the Pacific mackerel tapers at both ends. They have a pointy head and a large mouth. The head is dark blue, the back is dark blue with about 30 dark wavy lines, and the undersides are silver green. Pacific mackerel can be distinguished from other mackerel by counting the finlets on their back; Pacific mackerel typically have four to six finlets.

Biology

Pacific mackerel grow fast, up to 25 inches and more than 6 pounds. They can live up to 18 years but are able to reproduce by age 4, and sometimes as early as age 1. They spawn at different times of the year, depending on where they live. Pacific mackerel spawn from late April to September off California, year-round off central Baja California peaking from June through October, and from late fall to early spring off…

Where They Live

Range Pacific mackerel are found from southeastern Alaska to Mexico but are most common south of Point Conception, California. Habitat Pacific mackerel live within 20 miles of shore in water ranging from 50˚ to 72˚ F. When the population is small, they tend to occupy only the warmer part of their habitat. Juveniles live off sandy beaches, around kelp beds, and in open bays.

How to Buy & Source

Availability

Year-round, but primarily in summer.

Source

U.S. wild-caught from Washington to California.

Commercial Fishery & Harvest

Commercial fishery: In 2024, commercial landings of Pacific mackerel totaled 3.3 million pounds and were valued at $800,000, according to the NOAA Fisheries commercial fishing landings database . There is no directed fishery for mackerel in Oregon or Washington, but small amounts are taken incidentally by whiting trawlers and salmon trollers. Gear types, habitat impacts, and bycatch: Round haul nets are used to catch Pacific mackerel. Habitat and bycatch impacts are minimal because the gear is used at the surface. Recreational fishery: Recreational fishermen catch Pacific mackerel in California but seldom target them. The statewide recreational harvest makes up a small fraction (less than 5 percent in weight) of the total landings.

Sustainability Story

Not Overfished Stocks Stable Smart Choice

U.S. wild-caught Pacific mackerel is a smart seafood choice because it is sustainably managed and responsibly harvested under U.S. regulations.

Stock Structure

Pacific mackerel is not overfished (2023 stock assessment), and not subject to overfishing based on 2023 catch data. Summary stock assessment information can be found on Stock SMART . Pacific mackerel naturally experience “boom and bust” cycles of abundance, which is typical of other small pelagic species that have relatively short life spans and high reproduction rates.

Population

The stock is not overfished.

Fishing Rate

Not subject to overfishing.

Habitat Impacts

The gear used to catch Pacific mackerel is used at the surface and has little impact on bottom habitat.

Bycatch

Bycatch is low because gear used is selective.

Management

NOAA Fisheries and the Pacific Fishery Management Council manage the Pacific mackerel fishery. Managed under the Coastal Pelagic Species Fishery Management Plan : Catch limits are in place to end and prevent overfishing. Permits are needed to harvest Pacific mackerel. Gear restrictions are in place to reduce bycatch.
